Be it known that we, LAUREN E. CRANE and THERON H. BLY; citizens of the United States, residing at Minneapolis, in the county of Hennepin and State'of Minnesota, have invented certain new and useful Improvements in Smoke-Ejectors; and we do hereby declare scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide an improved apparatus for ej ecting smoke or fumes by im ulses and preferably in the form of rings; an it consists of 'the novel devices and combinations hereinafter described, and defined in the claims. v

The ap aratus is adapted to take different forms and) is adapted for a great many different uses. For instance, it is especially well adapted for diffusing disinfecting, germ an insect destroying smoke and fumes, and it isalso adapted for use as a toy or advertising medium for shooting smoke rings into the air, all as will be hereinafter more fully described. y

The invention is illustrated in the accompanying drawings, whereinv like characters indicate views. A

Figure 1 is a view in side elevation, showing the im roved apparatus in the form of a cannon. ig. 2 is a vertical section taken centrally through the a paratus shown in Fig. 1 from front to rear t ereof, and Fig. 3 is an enlarged* transverse vertical section taken .through the device on the line x3 m3 of Fig. 2.

Referring first to the construction illustrated in Figs. 1, 2, and 3, the numeral 1 indicates the barrel of the'toy cannon, the same being rigidly supported by a box-like base 2. The numeral 3 indicates a drawer-like fireboX which is removably fitted into a compartment 4 in the upper forward ortion of the base 2. This fire-box is provi ed with a perforated false bottom 5, below which is an air-inlet duct 6. 'The compartment 4 opens into the barrel 1 througha plurality of perforations 7, as best shown in Fig. 2. These passages 7 permit the smoke from the burn-y ing material z, contained within the fire-box 3, to pass upward into the intermediate portion of the barrel 1. The extreme outer end of thebarrel 1 is provided with a con-` like parts throughout the several.

perforations 7, is a yielding diaphragm 9, preferably constructed of thin spring metal and secured to the barrel only at its upper portion, so thatits lower portion is free to vibrate. In the barrel 1, slightly rearward of the diaphragm 9, is a crescent-shaped flange 10,- which is secured to the lower portion of said barrel. passage of air betweenv the barrel and the loose portionI of the diaphragmQ.

Mounted on a frame 12 secured within the base 2, is a spring-motor, (indicated as an entirety tor may be of the usual or any suitable construction, but is arranged to im art rotary motion to a wheel or disk 14, whic has a plurality of laterally-projecting circumferentially-spaced cam-pins-15. Mounted in the u er portion ofthe frame 12 is a short rockshaft 16, which carries anu wardly-project The hammer 17 projects upward through the perforation 11 of the barrel 1, and its head stands in position to strike against the diaphragm 9, approximately at its center. A s ring 19, attached to the hammer 17 and to t e frame 12, tendsto force the head of the hammer' against the said disk. The lower end of the trip-arm 18 stands in position to be engaged in succession b the cam-pins 15 of the motor-driven whee 14. As shown, the spring ofthe motor 13 is ada ted to be wound in the usual Way or after the manner of an ordinary clock -spring by means of a key 20. j

As vis evident, when the spring-motor is tated the cam-pins 15 comin into en agement with a trip-arm 18 will orce the ammer 17 away from thel diaphragm 9 and then upon passing out of 'engagement with said arm will release the hammer and ,permit the head thereof to be thrown against vthe diaphragm by the spring 19. In this way the diaphragm will be v'brated with sudden impulses and for eachimpulse will eject from the barrel 1, through the contracted nozzlepassage 8, a puff of smoke which, as has been found in practice, will take the form of a tice that for each time the diaphragm 9 is struck by the hammer it will make two, and sometimes three, vibrations, thereby frequently ejecting two and three smoke-rings in very rapid succession. When this toy cannon is thus put into action and caused to ing hammer 17 and a depen ing trip-arm 18.-
